MCP is an open protocol that standardizes how applications provide context to LLMs. Think of MCP like a USB-C port for AI applications. Just as USB-C provides a standardized way to connect your devices to various peripherals and accessories, MCP provides a standardized way to connect AI models to different data sources and tools. > [Reference for details](https://modelcontextprotocol.io/introduction) ## TinyMCP supported system platforms * Windows * Linux * MacOS * Android * Other platforms that support standart c++... ## Usage Guide Please check the [wiki](https://github.com/Qihoo360/TinyMCP/wiki) for more information. ## Dependencies [jsoncpp 1.9.5](https://github.com/open-source-parsers/jsoncpp) ## MCP protocol version [MCP Specification 2024-11-05](https://modelcontextprotocol.io/specification/2024-11-05/index) ## Code structure brief | directory | brief | | --- | --- | | Public | SDK public directory, used to store global type definitions, global constant resources, helper classes, etc. | | Message | Definition and implementation of the basic data structures of the MCP protocol, mainly including the implementation of protocol data such as standard requests, responses, and notifications that follow the JSON-RPC 2.0 protocol. | | Session | Definition and implementation of MCP protocol interaction sessions, mainly including the implementation of stateful sessions based on the C/S architecture and the maintenance of the complete MCP session lifecycle (initialization phase, running phase, and closing phase). | | Transport | Definition of data transmission channels between various endpoints based on the C/S architecture, which also includes an implementation of a default stdio transmission channel. | | Task | Definition and implementation of various MCP tasks, such as the three - way handshake and capability negotiation task during the initialization phase, and the processing tasks for major requests like Prompts, Resources, Tools, etc. Time - consuming tasks are executed asynchronously, while ordinary tasks are executed synchronously. | | Entity | Definition of various protocol entity classes for MCP, mainly including the base class of the Server following the Singleton pattern. | ## Feature support brief > Although not all features of the MCP protocol have been implemented, it is more than sufficient for you to implement your own MCP Server. | Feature | Remarks | Essential Features | Supported or not | | --- | --- | --- | --- | | Base Protocol | Core JSON-RPC message types | Yes | Yes | | Lifecycle Management | Connection initialization, capability negotiation, and session control | Yes | Yes | | Transports | stdio | Yes | Yes | | Cancellation | Cancellation of in-progress requests through notification messages. | Yes | Yes | | Progress | Progress tracking for long-running operations through notification messages. | Yes | Yes | | Tools | Tools enable models to interact with external systems, such as querying databases, calling APIs, or performing computations. | Yes | Yes | | Resources | Resources allow servers to share data that provides context to language models, such as files, database schemas, or application-specific information. | Yes | Yes | | Pagination | Pagination allows servers to yield results in smaller chunks rather than all at once. | No | Yes | | Ping | Ping mechanism that allows either party to verify that their counterpart is still responsive and the connection is alive. | No | Yes | | Custom Notifications | JSON-RPC 2.0 notifications that are sent by an MCP Server or Client using custom method names, intended for transmitting arbitrary business data. | No | Yes | | Prompts | Prompts allow servers to provide structured messages and instructions for interacting with language models. | No | Yes | | Completion | A standardized way for servers to offer argument autocompletion suggestions for prompts and resource URIs. | No | Yes | | Logging | A standardized way for servers to send structured log messages to clients. | No | Yes | | Transports | HTTP with Server-Sent Events (SSE) | No | Not yet | ## LICENSE TinyMCP is licensed under the MIT License -
